The control of individual quantum systems is now a reality in a variety of physical settings.
Feedback control is an important class of control methods because of its ability to reduce the …

Abstract The Baryon Antibaryon Symmetry Experiment (BASE) aims at performing a
stringent test of the combined charge parity and time reversal (CPT) symmetry by comparing …

The control of individual quantum systems promises a new technology for the 21st century-
quantum technology. This book is the first comprehensive treatment of modern quantum …

The motion of a mechanical object, even a human-sized object, should be governed by the
rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult …

In real-time quantum feedback protocols,, the record of a continuous measurement is used
to stabilize a desired quantum state. Recent years have seen successful applications of …

Measurements with a one-electron quantum cyclotron determine the electron magnetic
moment, given by g/2= 1.001 159 652 180 73 (28)[0.28 ppt], and the fine structure constant …

Over the last quarter of this century, revolutionary advances have been made both in kind
and in precision in the application of particle traps to the study of thephysics of charged …

The masses of the lightest atomic nuclei and the electron mass are interlinked, and their
values affect observables in atomic, molecular,–and neutrino physics, as well as metrology …

We report on the precise measurement of the atomic mass of a single proton with a purpose-
built Penning-trap system. With a precision of 32 parts per trillion our result not only …

Precise knowledge of the fundamental properties of the proton is essential for our
understanding of atomic structure as well as for precise tests of fundamental symmetries. We …
